fiat panda remote key replacement Panda Key Fob Replacement

fiat 500x Key Fob Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors and start the engine. The fob might stop working for a variety.

The most common cause of key fob malfunction is the battery of the coin is dead. Other causes are water damage or a malfunctioning module and interference signals.

Dead Coin Battery

If the battery in your key fob has gone out of service, the first step is to replace it. Use a brand new button battery that has exactly the same size, voltage and specification as the previous one.

If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned prior to being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will help.

If the key fob doesn't working even though it is not exposed to water it could be due a malfunction in the receiver module or internal electronic chip. Reprogramming the keyfob using an OBDII scan could aid in these situations.

Water Damage

If your key fob took submerged in a pool or puddle, or taken a trip down the washing machine, it could have some water damage. You can usually be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to let the board completely dry before putting in the battery.

If your key fob has stopped working, even after replacing the battery and reprogramming it, you may have a malfunctioning receiver module. Reprogramming instructions are available for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This can be caused by dropping the key fob or due to exposure to water. If the key fob stops working after exposure to water it may be possible to repair it by cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob does not respond to cleaning, it is possible that the module has an issue and should be replaced. A defective receiver module could also cause the remote control key to cease functioning. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in the key fob is a crucial part of the anti-theft system in your car. It sends a message to the immobiliser inside your car to inform it that the key is valid. If the chip is damaged or broken, your car won't start.

A damaged chip could be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this case you'll need an entirely new key fob.

Faulty battery contacts

The battery contacts in the key fob are delicate and can get damaged with hard usage. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules in the car.

Modern fobs are constructed with rubber seals to keep out water. In the event of submerging them in water, even if just a light drizzle or splash, can damage the chip's electronic components.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle in order to start it. This system uses crypto coding systems in vehicles that are more modern and the older red key system in older ones. If the chip is not working properly it must be replaced.

A faulty 12 Volt battery

A faulty battery can cause the fiat punto key replacement fob to cease to function. When this occurs the car's computer will not be able to recognize that the remote is inside the vehicle.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly it is time to replace the battery.

Set an electrical load for a few seconds on the battery to determine its capacity. This will remove 1% of the surface charges. Then, measure the voltage again. The longer the battery is able to hold its voltage and the higher its capacity. It should be close to 12 volts several minutes.

Radio Signal Faulty Radio Signal

This is the main reason for keys not sending signals to vehicles. This problem can be solved by replacing the battery. It is however important to choose a battery with the same voltage and size as the original.

The buttons are not impervious to destruction and can take a lot. The battery buttons and contacts are delicate which means they could be bent or broken by rough usage.

Other objects or transmitters using the same frequency may also disrupt the signal. For instance, a lighting control panel close to your home can send interference over the same frequency that key fobs utilize. This could affect the fiat ducato remote key programming control of your car.

Faulty OBDII scan tool

There are many reasons why a scan tool might not work. Some are more complex than others.

Professional scan tools enable mechanics to monitor the car's network and run various self-tests. They can be huge time-savers, but they can be expensive, and beyond the budget of most DIYers.

If your OBD2 scan tool doesn't turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape, it's likely that a fuse has been blown. This is the main reason for failure of the scan tool. The most straightforward fix is to replace the fuse which has blown.
